Mobile network operators (MNO) continue to expand into multi-technology, multigenerational networks such as with 3G, 4G-LTE, and Wi-Fi, yet they must continue to provide subscribers a consistent service experience regardless of the network to which they are connected or roaming into. The key for this, is the ability to authenticate subscriber identity across networks. Subscriber identity needs to be managed centrally, irrespective of the network the subscriber is connected to at that moment.

HPE I-HSS is a fully featured Subscriber Data Management (SDM) function that is based on User Data Convergence (UDC) architecture. With a network agnostic architecture, subscriber identity is continuously carried over no matter which access method is used, allowing delivery of an undisrupted service experience.
